CameraFi

CameraFi transforms your Android phone into a live monitoring station for USB cameras. Connect microscopes, endoscopic cameras, DSLRs, and compatible drones to your device via USB OTG and view their output in real time on your screen—no complicated setup required.

The connection process is straightforward. As long as your Android device supports USB OTG, you can plug in any compatible camera and start viewing its feed almost immediately. The app handles the handshake between your phone and the camera hardware, eliminating the need for specialized software or drivers on your end.

Multiple resolution options let you balance image quality against performance. Choose SD quality (640×480) for faster streaming and lower bandwidth use, or step up to Full HD (1920×1080) for sharper details when sharpness matters. Audio transmission works alongside video, so you capture sound and vision together without additional configuration.

Drone operators benefit from real-time image feeds on their smartphone. If your drone is compatible with this app, you can monitor its camera output live during flight—a major advantage for aerial inspection, mapping, or creative work where a second screen helps you frame shots or spot obstacles.

The app is free to download and use, with a paid option to remove ads and unlock additional features. Note that video recording is not supported on Android Nougat; newer Android versions work without this limitation.

CameraFi works best on devices running Android 4.0 or higher with active USB OTG support. The lightweight footprint means it won't slow down your phone while a camera feed streams in the background.

Whether you're conducting microscope inspections, monitoring endoscopic procedures, testing DSLR setups before a shoot, or piloting a drone, CameraFi delivers a fast, no-fuss way to see what your camera sees—right on your Android device.
